Complementing the growing list of editions and translations which have appeared in the series Aristoteles Semitico-Latinus, this is the first critical edition of Adam of Bockenfield's commentary on the pseudo-Aristotelian treatise on plants. The leading Arts master at Oxford in the middle decades of the thirteenth century, Adam crafted a comprehensive and highly organized commentary, which enjoyed wide circulation on the continent. Professor Long's introduction also explores the relationship between Adam's commentary and the gloss that was the established classroom text at Oxford.

Genesis 16 tells of Abraham conceiving Ishmael with his wife Sarai's servant Hagar. Dominican Friar Richard Fishacre (ca. 1200-1248) used this Biblical narrative to explore the relationship of the natural and Divine sciences. Hagar's Vocation is a collection of fifteen essays which focus on the contributions of Fishacre, the first Dominican theologian at Oxford to have left a written legacy.
